Striations are grooves or furrows scratched into natural surfaces by vast geological movements. They are formed over thousands of years as great tracts of glacial matter shift across the landscape, dragging coarse gravel and other sediment with them. As the rock surface is scraped by debris, it is scoured and polished, as well as scored with deep grooves – grooves that mark the progress of some of nature’s most macroscopic and sedentary processes. Many of these images were taken at well known canyons in the US: Antelope Canyon near Page, Arizona, or the Paria Canyon set within the breathtaking Vermillion Cliffs and fed by the Colorado River.
